The COLORRESDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogColor::DoModalColorRes function. After the user closes the dialog box, this structure is updated with information about the user's selections.
Size of this structure, in bytes. Use the sizeof operator to calculate this value.
Ignored.
Flag that indicates the initial zoom level for previewing the image. Possible values are:
| Value | Meaning |
|---|---|
| TRUE | Set the initial zoom level to "Zoom to fit". |
| FALSE | Set the initial zoom level to "Normal (1:1)". |
A variable to be updated with the bits per pixel value entered in the dialog. Set this to indicate the initial value for the dialog.
A variable to be updated with the color resolution flags entered through the dialog. Setting this before calling the function has no effect. This will be one of the following:
| Value | Meaning |
|---|---|
| CRF_FIXEDPALETTE | [0x01] Use the fixed palette. |
| CRF_OPTIMIZEDPALETTE | [0x02] Create an optimized palette. Or, if you supply a palette in the pPalette or hPalette parameter, but not both, supply optimized colors for specified entries in the palette. |
| CRF_NETSCAPEPALETTE | [0x40] Use the fixed palette that is employed by Netscape Navigator and by Microsoft Internet Explorer. |
| CRF_USERHPALETTE | [0x0100] Use the palette specified in the hPalette parameter. |
| CRF_IDENTITYPALETTE | [0x08] Insert the Windows system palette. |
| CRF_BYTEORDERBGR | [0x04] Use BGR color order. This flag only has meaning when going to 16 bits per pixel or higher. |
| CRF_BYTEORDERRGB | [0x00] Use RGB color. This flag only has meaning when going to 16 bits per pixel or higher. |
| CRF_NODITHERING | [0x00000000] Use nearest color matching. |
| CRF_FLOYDSTEINDITHERING | [0x00010000] Use Floyd-Steinberg dithering. |
| CRF_STUCKIDITHERING | [0x00020000] Use Stucki dithering. |
| CRF_BURKESDITHERING | [0x00030000] Use Burkes dithering. |
| CRF_SIERRADITHERING | [0x00040000] Use Sierra dithering. |
| CRF_STEVENSONARCEDITHERING | [0x00050000] Use Stevenson Arce dithering. |
| CRF_JARVISDITHERING | [0x00060000] Use Jarvis dithering. |
| CRF_ORDEREDDITHERING | [0x00070000] Use ordered dithering, which is faster but less accurate than other dithering methods. |
| CRF_CLUSTEREDDITHERING | [0x00080000] Use clustered dithering. |
A handle to a palette to be updated with a custom palette entered through the dialog. This member is valid only when CRF_USERHPALETTE is set in uColorResFlags.
